STRIKING APPARATUS FO'R CLOCKS AND ALARM/S.

SPECIFICATION forming part of Letters Patent No. 284,583, dated September 4, 1883. Application filed April 2S, 1383. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, Isaac B. VOODRUFF, of XVinsted, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Striking Apparatus for Clocks and. I 'do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invent-ion relates to an. improvement in clocks, the object being to provide novel striking apparatus therefor.

\V ith this object .in view my invention consists, essentially, in the combination, with the striking mechanism of a clock, of a swinging bell rung by motion transmitted to it from the striking mechanism.

My invention further consists in certain details ofcoi'istruction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of a clock embodying my invention; and Fig. 2 is a view thereof, partly in vertical section and partly in elevation.

The clock-case A, which may be of any design and construction, is surmounted by two hollow standards, I3, which communicate with the interior of the clock-case through orifices C, formed in the top I) of the case. rIhe upper extremities ofthe said standards are provided with open slots E and with perforations F, the same being adapted to receive the j ournals G of the yoke H, to which. the bell I is secured, the journals being` retained in place in their bearings by means of ornamental caps J, fitting over the tops of the standards. By removin the said caps and springingthe yoke a little, the bell and its attachments can be ylifted from the standards `for purposes of repair, and for packing the clock for transportation.

The bell is provided with a swinging tongue, K, which is interposed between two springarms, Il, arranged to receive and absorb the recoil of the tongue and lessen its vibration. Drums M, located on the journals aforesaid, are perforated for the attachment of cords N, which are respectively wound in opposite directions. The said cords N are also attached to the upper ends of thin Vflat plates O, each of the same being provided with a vertical series of perforations, I, enabling them to be adjustably engaged with studs Q, located on the opposite ends of a lever, Ri, fulcrumed midway of its length to a bearing, S, secured to the clock-case, or to the clock mechanism itself. The plates are prevented from disengaging from the studs by means of springarms T, pivotally secured to the lever It, and having their outer ends perforated to fit over the ends of the studs, the plates O being thus retained therein. The said lever R is rocked on its fulcrum to alternately elevate and depress its ends by motion transmitted from the striking mechanism of the clock U, through a pitman, V, and a crank-arm, XV, the latter being rigidly secured to the arbor of a pinion of the striking-train, and said pinion being arranged to impart those motions to lever R necessary to ring the bell appropriately with respect to the heur.

As already mentioned, the cords N, respectively attached to the drums M, are wound thereupon in opposite directions, whereby the bell is alternately swung to and fro by the rocking ofthe lever R.

Although the bell is preferably provided with a tongue, the same may be dispensed fwith, and its function performed by hammers located on one or both. sides of the bell.

If desired, idle figures or devices may be arranged to be operated-by the motion of the bell, and thus produce novel effects. The iigure of a man arranged to apparently pull a cord and ring the bell is an instance of such an arrangement.

It is apparent that any striking mechanism may be adapted to fulfill the requirements of my invention, and also that the mechanism employed for converting the motion of the striking mechanism into an alternately swinging motion of the bell may assume many different forms. I would therefore have it understood that I do not limit myself to the exact construction shown and described, but that I hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters,

Patent, is`

l. The combination, with the striking mech- IOO anism lof a clock, of a bell attached to a yoke `journaled in suitable bearings, and devices connecting the yoke and striking mechanism, for imparting a positive motion in opposite directions to the bell, and ringing it, so as to denote the hours of the day, substantially as set forth.

2. The combination, with the striking mechanism of a clock, of a bell attached to a yoke journaled in suitable bearings, drums located on the yoke, cords attached to the respective drums, and devices connecting the cords with the said striking mechanism, substantially as` set forth.

3. The Combination, with thestrikng meehanism of a clock, of a bell attached to a yoke journaled in suitable bearings, drums locatedv on the yoke, ycords attached to andY wound in opposite directions on the drums, and adjustable devices for connecting the cords to the said striking mechanism, substantially as set forth. g t

4. The combination, with the strikingmechanism of a clock, of a bell attached to a yoke journaled in suitable bearings, drums located on-the yoke,kcords attached to the drums, a

lever fulcrum'ed midway of-- its length and having the said cords attached toits ends, and means to alternately elevate and depress the v ends of the lever by power transmitted from 3o the said striking mechanism, substantially as set forth.

5. The combination, with the striking mechanism of a clock, of a bell attached to a yoke removably j ournaled in hollow standards, and 3 5 ing witnesses.
